Epichlorohydrin Rubber
Epichlorohydrin (ECO) has properties similar to nitrile rubber but with better heat, oil and petrol resistance. It has a low gas permeability and better low temperature flexibility than NBR. Its resistance to acids, alkalis and ozone is excellent.
However, its poor compression set limits its use as a sealing material and its corrosive effect on metals can increase tooling costs and limit metal bonding applications.
Typical uses are in automotive fuel systems, bladders, diaphragms and rollers.
